California Work Pays Demonstration Project: County Welfare Administrative Data, 1992-1998, Public Use Version 4.1 (ICPSR 4207)

Summary:

The California Work Pays Demonstration Project (CWPDP) was
intended to assess the effects of recent changes in Aid to Families
With Dependent Children (AFDC) provisions. The project documents the
dynamics of family poverty and welfare use in California. Part 1,
Overview Data: Cases contains one record for each CWPDP case sampled
between October 1992 and March 1997. For each case, seven data

The California Work Pays Demonstration Project (CWPDP) was
intended to assess the effects of recent changes in Aid to Families
With Dependent Children (AFDC) provisions. The project documents the
dynamics of family poverty and welfare use in California. Part 1,
Overview Data: Cases contains one record for each CWPDP case sampled
between October 1992 and March 1997. For each case, seven data
presence indicator variables identify the presence of data in each of
the data file types. Four observation variables identify the number of
case-months records observed in the Four County Cases file, the number
of person records observed in the Four County Persons and Assistance
History Persons files, and the first month during which AFDC
participation is observed in the Assistance History Persons file.
Fifteen survey detail variables identify survey participation,
interview completion, respondent's person number and date of birth,
and the survey record number. Parts 2-5, Four County Data: Cases,
contain case-month records for all control and experimental cases
selected to be a part of the study between October 1992 and March 1997
for any month (beginning with the month selected) during which an
assistance unit received AFDC of food stamps. Each case-month record
contains county administrative data for eligible family size and type,
income, and cash and food stamp assistance amounts. These files are
identical to the Four County Data: Cases files in County Welfare
Administrative Data Version 4. Parts 6-9, Four County Data: Persons,
contain records for each person observed associated with any control
or experimental case selected to be part of the study between October
1992 and March 1997. Records include nonconfidential demographic
information and monthly values for aid type and eligibility. These
files are identical to the Four County Data: Persons files in County
Welfare Administrative Data Version 4. Parts 10-13, Assistance History
Data: Aggregate, contain case-month records that summarize information
for the months of January 1987 through December 1996 about the public
assistance program participation and eligibility of persons associated
with sampled cases. This dataset was constructed from the Assistance
History Data: Persons datasets (Parts 14-17) that contain persons
associated with the study units. Parts 14-17, Assistance History Data:
Persons, contain the Medi-Cal and program participation history of
each person associated with the assistance units for cases selected
between October 1992 and March 1997. This dataset does not include
information about persons who left the assistance unit before the
month sampled. Each record includes program participation information
for each month from January 1987 through December 1996, a total of 120
months, as well as demographic information. Parts 18-21, Medi-Cal
Payments Data: Cases, contain one record for each case selected to be
part of the CWPDP sample between December 1992 and March 1997. This
dataset contains the Medi-Cal payments made for each case in the study
for the month of December 1992 and quarterly from 1993 through the
fourth quarter of 1997. University of California Data Archive and
Technical Assistance receives this data from California Department of
Social Services-Research Branch (CDSS-RB) by quarter (not month),
aggregated to case number. Therefore, the data in these files are
aggregated payments information for all assistance units with the same
case number, whether or not that assistance unit is part of the CWPDP
sample. These files are identical to the Medi-Cal Payments Data: Cases
files in County Welfare Administrative Data Version 3.

Universe:
Administrative welfare records from Alameda, San
Joaquin, San Bernardino, and Los Angeles Counties between 1992
and 1998.

Data Types:
survey data,
administrative records data

Data Collection Notes:

(1) Administrative data, such as the files represented
here, must be viewed in light of the original reasons for which the
data were collected, as well as the original data systems used to
collect and store the data. These data were collected for the purpose
of administering a state assistance program. Without some
understanding of the context of Welfare programs in California, users
of these data may have difficulty conducting contextually meaningful
analysis. Because of the interrelated nature of the files represented
here, users are strongly advised to examine carefully the entire set
of available files before beginning analysis. (2) The principal
investigator delivered this data with the following note about the
current version: This Version 4.1 of the County Welfare Administrative
Data replaces all previous versions. The files in Version 4.1 correct
a coding error in both the Version 4 Assistance History Data:
Aggregate files and the Version 4 Assistance History Data: Persons
files. Variables in the Overview Data: Cases files that relate to
these two sets of data were also changed to reflect the corrections
made to the Assistance History Data files. Also note that the files in
Version 4 cover a longer data period than in Version 3. Four County
Data files now contain 12 additional months of data through September
1998. Assistance History Data files contain two additional years of
data.

Methodology

Sample:
Cases were sampled from the administrative welfare records
sent by each county to University of California Data Archive and
Technical Assistance.

Weight:
For original sample cases, the weight was based on the
sampling interval. The weight variable for additional sample cases was
modified to account for undersampling of new sample cases due to the
delayed entry of cases into the Medi-Cal Eligibility Data System (and,
therefore, into the sampling pool). In Version 4, two weights were
included for each case: the Sampling Interval Weight and the County
Caseload Weight. The Sampling Interval Weight is the original weight
implied by the sampling method. The County Caseload Weight is the
weight needed to expand the original sample to the December 1992
caseload (for county-aid code cells) and to expand the additional
samples to the number of new approvals (for county-aid code cells)
during the sample month. Using state administrative data, County
Caseload Weights were calculated by the principal investigator staff
to reflect the number of AFDC cases a sample case represents.
Expanding the original sample cases by using the County Caseload
Weights, more accurately reflects the caseloads of the counties during
December 1992. Similarly, expanding the additional sample cases by
using the County Caseload Weights, more accurately reflects the number
of new cases in the counties during the month selected for sample.
After December 1992, it is not possible to weight up samples to
determine county caseloads since certain types of cases were excluded
from sampling. Additional sample cases can only be expanded to the
number of cases new to welfare during the study period.
